The present invention relates to a economic synthetic method of
2-deoxy-L-ribose from 2-deoxy-D-ribose with easy reaction, separation and
purification. The present invention consists of four (4) steps including
protection, activation 3-and 4-OH groups, inversion and deprotection
step. In respect to the cost for equipment, reagent and operation, by the
present invention, 2-deoxy-L-ribose can be produced more economically
because the invention uses 2-deoxy-L-ribose which is abundant in nature
and easily synthesized from D-glucose, and adopt simple and yielding
process.
